Abstract: A dog boot having as particular portions a foot, ankle and calf, the calf and ankle being large enough to accommodate the dog's paw passing through. The front of the boot calf has a vertical opening, and there is provided a vertical panel, free at the top, providing a tongue for covering the vertical opening in both an open or relatively closed condition, for insertion and removal of the dog's leg from the boot. A horizontal belt is fastenable at optionally chosen vertical places along the back of the boot; and a vertical strap affixed to the boot along the rear portion of the calf provides both a carrying strap and a cover to guard against snags of the hook-like Velcro area which provides the holder body for the horizontal belt. Other features add to the boot's advantages.
